SIM on chip or eSIM cards do the exact same job as a normal IoT SIM card. Neverthelesss, eSIM cards are permanently stored inside a device. An eSIM is usually attached by soldering to the PCB. eSIMs prevent people from tampering with the device or changing the device it sits in. This helps enhance the […]

15th. November 2018, Munich, Germany Time 17:00 – 18:00 Session/Workshop Speaker: Roger Denker, MegiQ BV Language: English Registration (soon): https://www.wireless-congress.com/home.html In 60 minutes you will learn how easy it is to use a PC-based Vector Network Analyser (VNA) made by MegiQ. Examples to be presented at the Antenna Tutorial Part 1 will include live measurements […]

As Freddie Mercury sang: “The show must go on”. After our Successful NB-IoT Roadshow with stops between Berline and Vienna in 2017, we return to Berlin on June 28th. “Berlin ist eine Reise wert” (“Berlin is well worth a visit”). June 28th is a Thursday. so anyone who will can take Friday as a day […]

NB-IoT reference design in credit card size including PCB track antenna The wireless IoT market is crying for small mobile devices transmitting for years from tiny batteries. With akorIoT Nano we developed the next open design. “akor” is the Proto-Celtic word for “open”. With placing the order for akorIoT Nano you get the schematic diagrams, […]

After comparing NB-IoT, LoRaWAN and SIGFOX’s energy consumptions during transmission in the USA and Europe, here is another direct comparison with GSM and SMS. SIGFOX and LoRaWAN repeatedly call out their low energy consumption when compared to SMS with wake-up and registration on the GSM network. Their commentary is that the two unlicensed LPWAN technologies […]

The physics in US is the same than in Europe. The energy consumption of a radio transmitter is computed by multiplying the power output with time. LPWAN in the unlicend band in the US has not to follow a duty cycle but a maximum time of 400 ms per data package plus frequency happing. The […]

The energy consumption of a radio transmitter is computed by multiplying the power output with time. The graph clearly shows the envelope of various LPWA transmitters in Europe over time. In Europe SIGFOX and LoRaWAN are limited to 14 dBm TX power. SIGFOX and NB-IoT are along the right scale of time axis. However, in […]

The Germans are the masters of long words and long sentences with the verb at the end (frustrating simultaneous translators the world over). German datasheets are 30% longer, or in a font size so small they are hard to read. But, Germans are capable of short stories as well. To cut a long story short, […]

Why I wrote the IoT M2M Cookbook

In my more than 20 years working with a manufacturer and in distribution I gave the same hints and recommendations to developers of wireless applications again and again. In May 2012 I made the decision to write the story that I have to tell weekly to customers in a book. The target is to guideline developers from the idea for an IoT / M2M device to a final product with mass production.
